IMPROVEMENT IN TREADLBS.

The Schedule referred to in these Letters-Patent and making part of the sarna To all whom it may conce/rn: v

Be it known that I, WILLIAM S. Coos, of the cit-y of Rochester', in the county of Monroe and State of New York, have invent-ed certain new and useful linprovemeuts in the Application of Power, of which the following is a specification.

Nature of I nrentt'on..

This invention consists in' so arranging the operating parts as hereinafter described, that the same may be turned to any desired angle to present the tool or instrument properly to the work, either in front ot or at the side of the operator.

.General Description.

In the drawings- Figure 1 is an elevation ot' my improvement applied to a suitable frame.

Figure 2, horizontal section in plane a: a'.

Figure 3, a bottom view of the treadle and connections.

Figure 4, a perspective viewl of the same parts, a portion of the treadle being broken away.

A is a suitable frame of any desired kind.

B is a turn-table mounted thereon and sustaining the working parts.

To facilitate the turning of the table, friction-rollers a. a, of rubber or other material, are situated under the same, resting in a metallic plate or rim, C, or equivalent.

On the under side ot the table is attached the branching-alms l) l) of a bearing, D, whose hub o rests on a spindle, E, to which it is fixed at any dcsired height by a setfscrew, d. l

The spindle is stayed centrally by a scroll, (1, presently to be described, and is swiveled atthe lower end to the treadle-shai't- H, which has a bend or depression for that purpose.

The scroll consists simply o1' a metallic lcat' or band extendingV from side to side of the frame, to which it is attached by screw-bolts fj, which pass through vertical slots of the ends ofthe scroll, thereby alhuring a vertical adjustment.

At suitable points the scroll has upright braces jj attached to the bcd of the frame, and provided with similar screw and slot connections.

This vertical tuljnst1ne1|t,both ot' the` scroll and the bearing' '1), adapts the said parts to application on frames ot' ditte-rent heights. I

The central portion of the scroll is made concentric to any desired extent with the axis of the spindle, as'4 shown at g, and this concentric port-ion is cutwit-h a longitudinal slot, h, fig. 1.

Through this slot passes thc elbow of a right-angled hanger, l, attached at the nppcrcnd to the turn-table,

and at the lower or inner und to the spindle, with which it turns when the table is revolved.

The hanger is iixcd to the scroll at any desired position by any suitable arrangement, that shown in the drawings being a bent spring, K, attached to it, pressed np by a nut, i, on `screw 7.'.

A band-wheel, L, is hung to hanger 1, and from crank r of this wheel a pit-man-rod, M, extends down and has pivotcd to its lowcr end a vertical jointpicce, N. i

This in.turn is jointed at right anglosto a horzon tal rock-plate, O, pivot-ed at on the under side ot' the treadle l.

The outer end of the rock-plate is formed into a clasp, m, that embraces the edge n of the treadle, which is made concentric with pivot lto preserve contact of the parts.

The rock-plate hasl an arm, p, wit-l1 an elongated eye in it, through which passes a heilt rod, Q.

This rod at the opposite end is swiveled in a joint-- piede,- R, which is horizontal, and in turn is pivoted in the lower end of spindle E.

The swivcled end of the rod simply turns in the jointed piece, and is retained by a screw, q, which sets into a groove in the same, or by s onie equivalent means.

Power applied tov the treadle AP is transferred by pitman M to band-wheel L, and thence transferred to pulley S or other part at pleasure.

When the turn-table is turned around the band-v wheel moves with it, also the spindle E.

The spindle carries with it the joint lt and bent rod Q. The end ot the bcnt rod sliding in the eye ofthe rock-plate U also draws that around on the treadl," and with it the joint X and pitman M.

Thus the whole working apparatus moves around simultaneously with the turn-table, and assumes just the anglo that that docs. thcretbre thc parts may be set at any desired position.

The double joints produced at thc pointsR and N,

insure a free action ofthe trcadle at whatever position the arrangement is sct, as the said joints have almost` a universal motion. There can bcl no cramping or binding under these circumstances.

This machine, thus arranged, is adapted to agrcat variety of purposes, such as operating drills, saws and other tools; also operating sewing-machines, Src. It enables the work to he done in almost any position or at almost any angle, thus not only facilitating t-he work and lcsscning thc labor and trouble, but also econoniizing space, as by this adjustment the machine may be sct ucar the wall instead of in thcl middle of the oor.

To facilitate the adjustment to the greatest degree, as well as to adapt the t-rcadle to dierent machines, l rest said treadle in ways Y Y, which allow it to be adjusted out or in, being held in any one position by set-screws t t.

A slot, u, is formed in the treadle, to allow such adjustment past the spindle.

The ways V form the bearings of the treadle upon the shaft, being swiveled thereto and held in place by sliding collars I WV, or equivalent.

It is obvious that instead of a treadle for the application of foot-power, any equivalent device for the application of heavier power .may be applied. In either case the same principle of adjustment of the operating parts would be involved.

Claims.

What I claim, and desire to secure by Letters Patent, is- '1 1. Arranging theoperating mechanism n combination with the turn-table and treadle, in such a manner that the whole may be turned simultaneously to any 5. The arrangement of the bent spring K, screw k -of the double joints N It, which allows a free action of said parts at whatever angle the operating mechanism is turned, as herein described.

9. The combination of clasp-lip on of rock-plate O with `the concentric edge n of the treadle, as described and for the purpose specified.

10. The combination ofthe swivelled ways V V and retaining-collars T W with the treadle, for accomplishing the proper adj ustmcnt of the same, as herein described.

ll. The arrangement as a whole, consisting of the,

turn-table B, bearing D, spindle E,'hanger I, scroll G, joints N R, rock-plate O, and bent rod Q, operating as described and for the purpose' specified.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses. WILLIAM S. GOON.
